PyQt5 QSpinBox – Adding background image for multiple states

In this article we will see how we can set background image to the spin box for its various states. There are basically three states of the spin box one is normal state, second is the hover state i.e when cursor is on the spin box and third is the pressed state i.e when mouse button is pressed.

In order to do this we have to change the style sheet associated with the spin box, below is the style sheet code

QSpinBox
{
border : 1px solid black;
background-image : url(image1.png);
}
QSpinBox::hover
{
background-image : url(image2.png);
}
QSpinBox::pressed
{
background-image : url(image3.png);
}

This will add three different background image for each state, there are also some additional states like anti-hover (!hover) and anti-pressed(!pressed) these are opposite of hover and pressed state respectively.

Note : We have to add border for the normal state else image will not get displayed as PyQt5 will not allow it to overwrite the style sheet

Below is the implementation

# importing libraries

from PyQt5 import QtCore, QtGui

import sys


class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)

        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)

        # setting range to the spin box
        self.spin.setRange(0, 9)

        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")

        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")

        # setting style sheet
        # adding background image
        # adding background image for hover and pressed state
        self.spin.setStyleSheet("QSpinBox"
                                "{"
                                "border : 2px solid black;"
                                "background-image : url(image.png);"
                                "}"
                                "QSpinBox::hover"
                                "{"
                                "background-image : url(skin.png);"
                                "}"
                                "QSpinBox::pressed"
                                "{"
                                "background-image : url(logo.png);"
                                "}"
                                )


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
